Anti-RITA antibodies enable researchers to detect and measure the RITA antigen in biological samples. This target is a reported synonym of the ZNF331 gene, which encodes zinc finger protein 331. This protein is known to function in the regulation of transcription, among other biological roles. The human version of RITA has a canonical amino acid length of 463 residues and a protein mass of 53.7 kilodaltons. It is reported to be localized in the nucleus of cells. RITA is a member of the Krueppel C2H2-type zinc-finger protein family.
